ARC Straightwire:

In this Grade, you improve your recall of the past markedly through an auditing style known as straightwire. It deals in getting you back in communication with things you've long since forgotten, using all your senses via straightwire recall; much like a conduit to the past using your perceptions, improving your recall and at the same time making you more causative in life and over your past. The result of this excellent auditing step is "knowing you won't get any worse."
